Title: Dyeable Carpet and Yarns therefor
Inventor: LEVESQUE RAYMOND ADRIAN
IPC: D01F8/08
Filed: 1967-03-21
Abstract: 1,180,587. Crimped yarns. AMERICAN CYANAMID CO. 21 March, 1967 [13 April, 1966], No. 13265/67. Headings D1F and D1W. Yarn is composed of staple bicomponent fibres of two or more acrylonitrile polymers each containing at least 70% acrylonitrile having the same hydrophilic properties of swellability but differential shrinkage capacities of 5-20%. The fibres have an irreversible helical crimp which has been temporarily removed by stretching but which is recoverable upon immersion in water at 200F. The yarn has twist such that in water at 200F it develops a specific bulk of at least 7.0 cc/g and a compressive bulk of at least 6.0 cc/g under a load of 18 g/inch of yarn, such bulk being maintained at a level of at least 6.0 cc/g when subjected to the forces imposed by repeated dipping of the yarn in water at 200F. The crimp is developed in the yarn after formation into a carpet e.g. under conditions of hot-wet dyeing or hot-dry or-wet treatment before dyeing, little or no further crimp occurring upon drying and the crimp is not affected by subsequent hot-wet treatment. The yarn may contain other fibres e.g. mono-component acrylic fibres, bicomponent fibres the components of which differ in hydrophilic properties, wool, nylon. The specific and compressive bulk values are determined by described tests.

Title: Apparatus for electrifying fences
IPC: H05C1/04
Filed: 1957-04-26
Abstract: 830,458. Electromagnetic interrupters. GRAY, G. W. April 11, 1958 [April 26, 1957], No. 13327/57. Class 38 (5). [Also in Group XXXV] An induction coil with a balance-wheel type of interrupter in its primary circuit, for electrifying fences, has an angularly adjustable iron bridge between pole tips of the magnetic core carrying the coils. As shown, the coil 10 has a core 9 connected to U-shaped iron pieces 12 with pole tips 12a. An iron bridge 13 is angularly adjustable about a central pin 11, and mounted above it on bearing 15 is an armature comprising a non-magnetic ring 14 with a diametrical iron piece 14a. The bearing 15 is insulated from the pin 11 by a sleeve 11a and washer 17. The armature carries a contact 18 which is normally held against a second contact 22 on leaf-spring 23 by a spiral spring 19 attached to the armature and to an adjustable arm secured to pin 11 by locking nut 21. The contacts are in series with the primary winding of the coil, which when energized causes the armature iron 14a to tend to align itself with pole tips 12a against spring 19, thus opening the contacts. The spring then restores the armature to its rest position, so reclosing the contacts, and the cycle is repeated. The frequency of oscillation can be controlled by adjustment of the bridge 13, which may also carry a projection to limit the travel. A capacitor is connected across the contact, and another may be connected across the supply. Coil 9 may be of square cross-section formed by four sets of laminations each arranged to overlap the side edges of an adjacent set, Fig. 4 (not shown). The contacts may be short-circuited by a push-button to ensure starting if they become tarnished.

Filed: 1973-03-20
Abstract: 1406175 Electric watches DAINI SEIKOSHA KK 20 March 1973 [21 March 1972] 13361/73 Heading G3T In an electric watch, movement of a setting stem 3, Fig. 1, to its outer position causes displacement of a lever 1 to bring a projection 1a thereon into contact with a friction disc 23 coupled to the gear train and to move a switching member 5 out of contact with a fixed pin 9, thus opening the watch driving circuit. As shown the lever 1 is pivoted at 2 and carries a pin 4 engaging a slot 5b in the member 5 which is pivoted on a pin 7 . A spring 10 biases the lever 1 to the switch open position. The gear train is an indirect centreseconds train in which a driving element (not shown) drives a fourth wheel and pinion (also not shown) and thus a third wheel and pinion 15, 14 which respectively mesh with a pinion 19 on a centre-seconds shaft 18 and a minute wheel 20 frictionally coupled to a cannon and pinion 21. When the stem is pulled out, the engagement of the disc 23 brakes the wheel 15 and thus the seconds hand shaft 18 and rotation of the stem causes setting of the minutes and hours hands (not shown) via a setting wheel (not shown) engaging the cannon pinion. Pushing in the stem frees the train and re-energizes the driving circuit.

Title: Gas-cooled gas turbine
IPC: F01D11/00
Filed: 1955-05-13
Abstract: 776,847. Turbines. SULZER FRERES SOC. ANON. May 13, 1955 [May 20, 1954], No. 13847/55. Class 110 (3). A multi-stage axial flow turbine in which a protective cooling gas is introduced into a labyrinth packing in the gap between the shroud ring or the equivalent of a stator blade ring and the walls of the rotor to prevent working fluid passing through the gap and to cool the surface of the rotor and in which the radial distance of the gap from the axis of the rotor is approximately the same as that of the inner ends of adjacent rotor blades has the part of the labyrinth packing lying upstream of the point of entry of the protective cooling gas arranged with a smaller resistance to flow of the cooling gas than the part downstream thereof. The hot working medium is supplied to the turbine through an annular space 1 to an annular flow channel 2. The stator guide blades 3, 4 fixed in a casing 5 have shroud rings 9 provided with labyrinth sealing rings 10 to form gaps 11, 12. Protective cooling gas which may be taken from the compressor of the gas turbine unit is led into a space 13 formed between the stator casing 5 and housing 14. A part of this gas is led to the roots of the guide blades 3 by bores 17, 18 in the casing 5. Bores 21, 22 supply another part of this air into the labyrinth gap 12. The bore 21 also constitutes a metering orifice which is so dimensioned that in normal operation a part of the protective gas issues from the gap 12 upstream of the blades 4. To maintain these conditions, the number of labyrinth rings downstream of the bore 22 is greater than the number upstream. Another part of the gas passes through a metering channel 23 into a collecting chamber 24 whence it is led through channel 25 into the labyrinth gap 11. Some of this gas passes into the working fluid upstream of the blades 3. The channels 22 and bores 23 should be distributed around the circumference of the casing.

Abstract: 456,586. Inductances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and CRAYMER, H. J., 37, Bishops Road, Chelmsford. May 11, 1935, No. 13916. [Class 37] A variable inductance for use, for example, as anode tuning coil in a wireless transmitter comprises a double helix of tubular conductor 3, a radial contact arm 13 for effecting continuous adjustment of the length of conductor in circuit, and a plurality of contact strips 20 for short-circuiting the turns of the conductor not in circuit. The contact arm 13 is fixed to an operating shaft 6 which has rotatably mounted thereon a panshaped copper member 17 carrying radially extending guides 19 spaced at 120. Slidably extending through each guide is a flexible contact strip 20 anchored at 20a to the frame of the coil and at 20b to a spider 22 slidable on the shaft 6. Thus longitudinal movement of the shaft due to the helical path of the contact arm 13 engaging the turns of the conductor causes the strips 20 to slide through their guides and bear on the turns between the contact 13 and the end of the coil. The pan 17 acts as a screen between the active and idle turns of the coil. Cooling fluid is circulated through the turns of the coil and may pass to the anode water jacket of the transmitter valve along one helix and back along the other.
